To all wiz omit may concern:

.Be it known that I,OALV1N Vos, a citi zen of the. United States, residing at New York, in the county of New York. and State 5 of New York, have invented certain new and useful Improvementsin Alloys, of which the following is a specification.

'This invention relates to an improvement in alloys. The main object of [the invention is "to produce an alloy to be used as anagent in the manufacture of steel for any. ur-

pose and for making iron and steel castmgs, which product possesses unusual tensile 1. strength and toughness, said alloy possessing degasifying and deoxidizing; properties 'and homogeneous product.

of unusual tensile strength and density, and

. which render the same of especlalvalue in the manufacture of 'a flawless product in which,su ch qualities and characteristics are particularly essential and of great value.

With the above named object in view,

this invention comprises an alloy includin the composition of metals hereinafter described and set "forth, and particlilarly pointedout in the claims. I 4 My improved alloy consists of aluminum 'within the limits of from 90. to 9.5 per cent; magnesium within the limits of from 2 to lfiper cent.-; sodium fluorid within the limits,

or cent; uranium of from'0.01 to 5' Patented June 21, 19,21. i

I when all of the metals have been properly nfixedand re duced to a molten mass, the constant gentle stirring action will cause such gases as may be contained in the molten metal to escape therefrom, thereby insuringaa more dense By means of the ingredients and my method hereinbefore referred to,"an intproved alloy is obtained which is possessed which is especially desirable in the manufacture of steel, and ironfand steel' castings where it is important that the productshall. possess flawless qualities and the maximum stren h. It will be evident that the vQc'ompounds mentioned do not remain in the finished alloy in the same proportions hereinbefore referred to, since the sodium fluorid serving as a fluxing agent will have substan tially disappeared, also some of the ferrosilicon and .a part'of the oxygen of the v uranium oxid, thereby forming a finished mately'from to per cent;; magnesium" the oxid, state within the limits. of 'from' a 0.01 tc 6 per cent.;1 and-ferrosilicon within the h its of fronr02 to 3 per cent.

-In t e manufacture 'of the alloy, ,my

35 method of-procedure isifas follows:

I first melt the aluminum in Zia suitable container, then apply 'heatto mistake tem-j what I' claim and desirev to secure by Letters- Patentis: 1. ,1.

I metals herein referred toare"thoroughly ring, the alloy produced is admirably. adapt- BO ed for use in degasify ing and deoxidizing steel and the ferrous groups of metals,thereby increasing the density .and eliminatingthe tendency of formationof flaws in the castings obtained from saidmetals.
